SamF: I reckon you could get away with a bit less SNRM as well.


That's the plan, but I want to take it slow. I'm still amazed you got it up to 9ish(?) without a drop in DLM profile. ;-)  I'm really hoping DLM isn't "broken" or something lol. 

Anyway, after a few days on -60 it seemed to end up with CRCPM a little over 3.

So now I just bumped up DownstreamMarginOffset to -65 on the Fritzbox, so a couple more data points below.  One interesting thing I note is that in "real" speedtests my upload speed seems to have been adversly affected by this latest tweak.  While download on most speedtests at -60 was 40.3Mbps and has now bumped up 40.9,  my upload which has been a very solid, consistent 9.4-9.5 for a long time, but has now dropped to ~9.1-9.2 with this latest tweak... not sure if it's actually related or not.

20120925    +20                14                33.9      0.06

Hmm, weird about your upload speed. I've never seen that before so maybe it's just a fluke. Tired a different speedtest server?

Looks like you're doing pretty well so far tho; ~10mbit up on your original speeds is pretty sweet! I reckon you might be able to get to 45mbit with a reasonable CRCPM.

As for the CRCPM limit, you have to put it in perspective. A CRCPM of 10 is actually 10 corrupted packets every minute, and considering you could easily see thousands of packets every minute, it's pretty small in terms of percentages.

Yeah, +10mbit is a nice gain. And that's true about the CRCPM, It's just funny how long I thought 1-2 might be the limit ;-)


CRCPM is still sitting around ~4.7, but I think I may be hitting the limits for my line. While actual SNRM has been pretty consistent since I started tweaking, generally staying flat and only occasionally varying by 1 db... now it looks like this:





PS: Yeah the speedtests were across a range of servers (auckland, wellington, christchurch and australian) Thoughput is very consistent and yeah it looks like the drop in upload was just a fluke or related to the time of day; within NZ it's pretty consistently back at 9.4+ this morning.

Hmm, yeah I saw that on my line at -6db:

Would be interesting to see if your line does the same as mine did...

So it looks like there's another member of the 17a club now...
I hadn't been to my brother's house for about a week and I see he's been switched over.

Not sure what prompted this, but I did change all the line settings to maximum stability about 1.5 months ago so maybe it was an extended period of low errors?

Uptime of 2 days, 8 hours;

Im pretty happy with my VDSL, never had a DLM forced resync yet even within the supposed 10 day training period, but did have quite a few power cuts due to faulty power,  



since snap did that change on their end last week i can actually max out the connection which is nice.

Good to hear! - and nice stats :) you can't really complain about maxing out a 65Mbps connection on copper :)

Interesting.  Any ideas what the line attenuation was before 17a?
It would be interesting to see what your stats look like back on +0db SNRM!

@Dan:  That is indeed a VERY sweet line!!

That looks sooooo good! I hope I get there too. How would set my modem to maximum stability settings also? Its an Innbox.

your modem seems to be a odd one, with the stats being incorrect and all..

have a hunt around, might an option somewhere.. otherwise DMT tools maybe?



heres what it looks like on the fritzbox, pretty sure SamF wrote somewhere what the options refer to in terms of modifications made..

I'm quite worried about my CRCPM being high - Am I going to get kicked off DLM-1?



Settings are default "Maximum performance" as the device arrived. Errors seem a lot higher than last week !

15 might be a tad high.. but you could be ok..

mine were about there (a tad lower from memory), i reacted with tweaking my snr to try and drop the rate, and triggered DLM to move back.. think im 1 move away from landing back to DLM-1

what i should have done, considering the error rates a few others have been getting with their tweaking, is tried just leaving it be and hope for the best.


depending on if you're more inclined in the speed rather than the latency  you might want to pull your performance settings down (unplug the modem first, make the change, leave it off for a good 5 mins to make sure DLM doesnt think its an unstable line - this is the step i missed unfortunately....)

Sam, have you been keeping track of this for everyone that's gone to 17a? I think highest pre-17a attenuation has been about 5 or 6, right?

@exDee: DLM is still a mystery to me, but If it was me I would probably tweak that intended SNRM down a notch or 2, but as hio77 suggests, ensure modem is unplugged from the line for a good 5 minutes at least while doing it. Having said that it would be very interesting to leave it and see if DLM does drop you down.



My line also seems to be ramping up on the errors front. Actually it's not looking too healthy, I think I may have found the limit of SNR tweaking. What do you guys think, should I push it further? :)
